study* After you have a preliminary understanding and mastery of installation process equipment, how can you continue to effectively improve your knowledge?

Even people who graduate with a major in chemical engineering may not necessarily be familiar with these things~~ This is a process. I think this must be based on the actual situation of your unit. While checking the information, you can also learn from the experienced workers and technicians.* . It's not a matter of one or two years. Everything is difficult at the beginning. Louzhu and I have the same problem. As long as we work hard, we will definitely succeed.

I did not study chemical engineering in college, and I also faced the problem of mismatched majors, but I think attitude is key. Only with a good attitude can you learn well. In addition, I think understanding is also very important in chemical engineering. This is a process of gradual accumulation. It is unrealistic to learn it well all at once! First of all, you must read more books and be familiar with the principles of chemical engineering. Secondly, you must combine more with your actual work. I believe you will slowly grow up!

Take your time, you have a lot of exposure to the chemical industry, and it is not profound, especially in a chemical factory.

I think the original poster just looks at it and doesn’t think about it. This way he doesn’t think deeply about it.: Why do pipes have this diameter? Why does the device need this parameter? Why is it arranged this way? Is there a better solution? Can various consumption be reduced? Then if you check the information based on these questions, you will naturally improve.

First, the poster needs to think about whether he will be inferior to others if he is not a chemical major. Second, the poster insists that he will not learn from what he has learned. He strives to take notes every day on what he feels confused and confused, and then make notes on the answers. Third, go to the site more often and learn about the equipment. * , the same equipment will have different forms and different usage requirements, and these cannot be taught in university books. ； Even an experienced chemical designer has to consult specifications for detailed design according to different design conditions. Experience can only tell him what kind of things are more appropriate to use under what circumstances, but cannot tell him the exact thing. ； For the same set of processes, people with different design experience will give different design ideas. However, these differences are all within the specifications, and the actual results may not be bad. What does this situation mean? There is not only one accurate answer to design. ； The specification will only tell you that this is not possible, and anything other than this is feasible, but a single piece of equipment must meet its supporting role in the entire process, not just on its own. . . In fact, many devices currently have room for tapping potential and increasing efficiency, so field engineers in factories will have a deeper understanding of a certain set of devices than design engineers in design institutes. . . Fourth, be good at expressing yourself. You don’t really understand until you understand something yourself, only if you let others understand it. Express your experience and you will be recognized by colleagues and leaders at work, and opportunities will naturally come. . Fifth, learn * Understand the principles of chemical engineering, which is the most basic book on chemical engineering. Not only do you know what it is, but you also know why it is so.

Well, after seeing your suggestions, I think they are very good, both in terms of methodology and practical guidance. I believe it is also a re-enlightenment and confirmation for me * route process. For example, the suggestion above, I usually think about, why is this pipeline so thick, why does this pipeline have to go this way, why is there a cross-line, why do I need a control valve on this line... This is about process thinking. I can ask the masters and engineers for advice, and generally I can get accurate answers. ； Regarding equipment or other things, we often ask why: Why are the pipelines made of this material? Why are ball valves chosen for valves instead of butterfly valves, gate valves, etc.? Why is the structure of this pump different from that one... This is a reflection on equipment and instrumentation. Although I asked the master why many of these, they were not sure, or their explanation was different from my own understanding. At this time, I wanted to check the information myself and find theoretical support. The question now is, when people usually encounter such problems, where do they usually look for information? Or what do you need to see? * * standard? Do you usually subscribe to magazines or books on this subject? Recommend it. Thanks! :$

Just look for information on this forum. There is a lot of useful information, just download it. There is also the "Chemical Process Design Manual", which covers a wide range of topics and can basically solve our basic problems. It is authoritative and practical! !

First, give yourself a position, see what direction you are interested in developing, and then pursue this direction. There are many devices in the workshop. You can find one device first and understand it thoroughly.

It doesn’t have much to do with those. Look at pictures more, help your teacher with work more, take the flow chart and run from door to door on site. Don’t just do it when working, think about it while doing it, think about why, and ask more why. Just like starting and stopping a large centrifugal pump, there are many steps, and you need to confirm many things before starting and stopping. Once you are familiar with the on-site operation, you will naturally understand a lot of things. There are also many valves. Why are we using this kind of valve? Why can’t oxygen pipelines be connected to flanges? Why should we add cutting valves? . . Think more about relationships. Once you master one device, it’s easy to learn others. Tanks, pumps, look at the flow chart and you will understand what they do and why they are placed where they are. I followed this idea and took down the air separation, vaporization, synthesis, unit and coupling alcohol, so don't worry, just calm down and study hard. The most taboo is to be impetuous, have high ambitions and low abilities, and not like to help others. It may take you a long time to think of a few words casually said by your teacher. Young people, study hard, the road is at your feet. Finally, I would like to remind you that you must pay attention to safety.

"Just calm down and study hard. The most taboo thing is to be impetuous, have high ambitions and low abilities, and not like to help others." Thank you!

Should think more. I think there are three steps to take. The first is to understand it, the second is to be able to do it, and the third is to consider why you are doing it and whether there is a better plan.

Everyone above has said everything that needs to be said. I will add one more important point, which I myself have deep experience with. I majored in geology, and now that I am doing ground engineering, I need to be familiar with various specifications, which is very helpful for my work. If I follow the specifications and then based on the actual situation, I can solve the problem. Four years of schooling is not as standard as two years of study! If you are engaged in design, you should be familiar with the specifications. At least you should know which specification to look for when designing something.

Well, some process flow designs are more complicated and have more ideas. Recently, we organized a discussion on PID diagrams, allowing everyone to put forward their own opinions, and we found many design flaws. As for some designs, there is controversy and no one is sure. At this time, you need to check the specifications and so on. The stage I'm at right now is that I don't know where the norms are. . . Hehe

After you have a preliminary understanding and mastery of process equipment, how can you effectively continue to improve your knowledge?

I had just graduated a year and a half ago and was fortunate enough to study in a newly constructed facility.* My experience is that when checking the process, you should compare it with the original designed process package, so that you can know the purpose of each pipeline valve. Check the PID diagram carefully and pay attention to some details. For example, the mixing point of the pipeline in the thermocouple should be 5 times or 10 times the pipe diameter. During start-up and shutdown, you should be flexible in your thinking when dealing with the process. For the same pipeline, do not be limited to the designed flow direction. There are often "reverse references" during our start-up process. Fortunately, I participated in two calibrations. This gave me a detailed understanding of various indicators of the device from operating parameters, material balance, energy consumption, conversion rate, etc. (because it needs to be calculated). Of course, not everyone has the opportunity to encounter start-up, shutdown, or even calibration. So how to learn for normal production devices. What the seniors above said is right, you need to be calm and don’t be frustrated. You should consult the masters more and learn. * . But I feel that these alone are not enough. Because there is too little work to be done during normal production, it is not enough to ask for advice when working. So you have to take out some procedures in the device to learn them. The simplest ones, such as the start and stop procedures of compressors or large pumps, go to the site to simulate every step of the operation, such as pointing to a valve and saying to yourself, I should open this valve first... If you go deeper, you can learn it. * Start-up and shutdown procedures... If you go a little deeper, you can think about why these steps are done as they are. If you don't understand, you can ask, either a master craftsman or an engineer, because they are the ones who wrote the procedures. Going a little deeper, you can think about whether this driving and parking step is optimal, and whether there are other ways to improve it. After you figure it out, you should discuss it with the master or engineer. Most of your ideas at this time are inappropriate, but you can learn why it doesn't work, and then you can directly eliminate these unworkable ideas and directly mention the ideas. Another point is to go to the forum more, I just discovered this. After all, the situations encountered by one device and one refinery are limited, but in the forum, everyone brought out their own experiences. We are equivalent to looking at the problem from the perspective of refineries across the country, which allows us to learn more.

The key is to straighten out your thoughts, clarify the master-slave relationship, delve into the details, and serve the overall situation. You will definitely make progress. Learn from the master but don't follow blindly. You must have your own thoughts and find opportunities to verify your own opinions. Theory guides practice.
